Abstract

The CBR value is influenced by soil gradation, mineral type, density and soil shear parameters. CBR testing is carried out on subgrade soil, but the undrained shear strength of the soil can also be used as a soil design parameter. Field shear strength tests that can be used to determine soil shear strength are DCP and Vane Shear. In contrast to DCP testing, shear strength testing is relatively quick and easy to determine soil properties to determine design parameters. Therefore, testing is needed to determine the correlation between the soil shear strength value and the CBR value to obtain a new equation that can be applied in the field. In this research, the CBR value was obtained through the Dynamic Cone Penetrometer test (DCP) and the soil shear strength of the vane shear test. DCP and Vane Shear testing was carried out at 10 test points in the Semarang area, Central Java. Laboratory testing is also carried out to validate soil types. The correlation obtained between the CBR value and the soil shear strength reached R = 0.8312. Based on this test, it can be concluded that the CBR value and soil shear strength value increase as the depth of the soil tested increases.

Abstract

Salah satu tantangan yang dihadapi mahasiswa yang berasal dari SMKN 7 Semarang adalah suasana pembelajaran dan sistem pembelajaran yang diterapkan PTV. Hal ini disebabkan karena adanya celah antara kurikulum SMK dengan PTV. Siswa SMKN 7 Semarang sudah memiliki pemahaman dasar terkait kompetensi bidang teknik sipil, tetapi ketika memasuki dunia PTV masih mengalami kesulitan dalam beberapa bidang. Oleh karena itu untuk menjembatani dan mengisi celah dari kurikulum SMK ke PTV diperlukan pengenalan dan pelatihan terkait kompetensi bidang teknik sipil, salah satunya adalah kompetensi pengujian tanah di lapangan.Pelatihan yang dilakuakn adalah pelatihan uji sandcone dan DCP. Hasil dari pelatihan siswa SMKN 7 Semarangdapat memahami secara tepat cara pengujian di lapangan menggunakan alat sandcone dan DCP, juga cara analisis data hasil pengujian. Selain itu, kuisioner juga menanyakan terkait kemudahan bimbingan selama pelatihan, hasilnya adalah 91% siswa menyatakan bahwa dosen dan mahasiswa yang mendampingi memberikan bimbingan dan arahan dengan jelas sehingga mudah dipahami oleh siswa.

Abstract

Community service in the form of implementing a system for checking and repairing cracks in walls in Pakintelan Village, Gunungpati District, Semarang City aims to increase residents' knowledge regarding the problem of cracks in walls which are thought to be caused by ground movement. This activity starts from a site survey, equipment preparation, and training carried out with the correct procedures, ensuring the implementation of correct repair methods and according to standards. Based on the results of surveys and interviews with local residents, the cracks in the walls of houses that occurred at the Citra Pesona Pakintelan Housing Complex were caused by ground movements which caused non-uniform structural settlement and vibrations resulting from housing construction behind the service location. The service team and students provide guidance and assistance to stone masons and the surrounding community. There were 6 masons who took part in the training and several members of the local community. The repair method used to repair cracked walls is the stitching method.

Abstract

SMKN 5 Surakarta students encountered a challenge during the initial assessment of the civil construction implementation, particularly concerning field soil testing. This challenge was exacerbated by the absence of soil mechanics courses in the curriculum. While the students possessed a fundamental grasp of civil engineering competencies, they faced difficulties in various aspects, with field soil testing being a notable area of concern. To address these competency gaps and enhance the vocational school curriculum, training sessions were conducted to educate students on the practical application of soil tests in the field. The specific training covered sand cone and DCP tests. According to the questionnaire results, post-training, over 50% of SMKN 5 Surakarta students exhibited a clear understanding of how to perform field tests using DCP, Sand Cone, and Speedy Moisture test equipment, along with the ability to analyze the resulting test data. The effectiveness of direct training and intensive mentoring was evident in facilitating students' comprehension of the provided material. Notably, 90% of the students affirmed that the training was easily comprehensible.

Abstract

The increase in the number of vehicles and economic growth in the city of Semarang puts significant pressure on road infrastructure. So it is necessary to prioritize maintenance on several road sections. This research uses the Treatment Priority Index (TPI) approach to identify road repair priorities in Tembalang District, Semarang City. Data on road conditions and daily traffic volume are variables in the TPI analysis and the data is analyzed using the Provincial District Road Management System (PKRMS). The results of the TPI analysis obtained road sections with critical conditions, especially Telumpak (TPI: 26.2) and Salak (TPI: 25.7). These sections require immediate repairs to ensure the safety and comfort of road users. This research provides a basis for information for policy makers to allocate resources efficiently, ensure sustainable road infrastructure, and support effective mobility in Semarang City, especially in Tembalang District.
